Abstract

The invention discloses an anti-back-tipping structural piece, an anti-back-tipping device and an engineering machine, and relates to the technical field of engineering machines. The technical problem that in the prior art, the damping effect is poor is solved. The anti-back-tipping structural piece comprises a seat body and damping particles, wherein the seat body is provided with a movable cavity and an embedding opening communicated with the movable cavity; the damping particles are arranged in the movable cavity in a filling manner and occupy partial space of the movable cavity, and the damping particles can dissipate vibration energy on a stretchable movement piece at least through the manners of friction of the stretchable movement piece embedded in from the embedding opening or non-elastic collision between the damping particles. The anti-back-tipping device comprises the stretchable movement piece and the anti-back-tipping structural piece provided in the invention. The engineering machine comprises an arm support, a rotary table, a propeller strut and the anti-back-tipping device provided in the invention. By means of the anti-back-tipping structural piece, the anti-back-tipping device and the engineering machine, the damping effect of the anti-back-tipping structural piece is improved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an anti-reclining structural member, an anti-reclining device provided with the anti-reclining structural member, and an engineering machine provided with the anti-reclining device. Background technique [0002] The dynamic tamping machine is a kind of frequent lifting of the rammer to a specified height, releasing the rammer through the decoupling device, and the huge energy generated after the rammer falls freely, which will generate strong vibration and impact on the foundation, thereby improving the bearing capacity of the foundation and reducing the impact of the foundation. Large-scale engineering machinery construction equipment with low settlement has been widely used in foundation treatment such as roads, railways, airports, docks, land reclamation from the sea, and backfilling in mountainous areas. [0003] Under the action of the decoupling device, the ra...
